Description
When using QtMqtt with thingsboard as a server then the fixed PUBACK header can end up with the reserved part being set to 2 which causes it to fail as it is expecting the reserved part to be set to 0. When it is set to 2 then it will fail with the message: Malformed fixed header for UNSUBACK/PUBACK/PUBREC/PUBCOMP.
